Genes affected

VPS11 (HGNC:14583): (VPS11 core subunit of CORVET and HOPS complexes) Vesicle mediated protein sorting plays an important role in segregation of intracellular molecules into distinct organelles. Genetic studies in yeast have identified more than 40 vacuolar protein sorting (VPS) genes involved in vesicle transport to vacuoles. This gene encodes the human homolog of yeast class C Vps11 protein. The mammalian class C Vps proteins are predominantly associated with late endosomes/lysosomes, and like their yeast counterparts, may mediate vesicle trafficking steps in the endosome/lysosome pathway. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]

The c.8C>T (p.A3V) alteration is located in exon 1 (coding exon 1) of the VPS11 gene. This alteration results from a C to T substitution at nucleotide position 8, causing the alanine (A) at amino acid position 3 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
